Hello everyone, this is my first time trying to root cuttings and I used Mai Mai 's bag method. It has been a week since I put them into the bag. Every two days I let them out for a few minutes. There's mist in the bag. However the cuttings seem very dry. Please advise what I did wrong. Many many thanks!

Don't make the environment too wet ( a 'mist' in the bag sounds pretty moist...) and don't put them in too warm a place. If the cuttings you use are pretty fresh it should turn out fine.
Good luck!

Thank you for advice. Here are some pics after I open the large bag and take the whole box out.
In the first pic, the cutting looks dried out.
In the second pic, there's mist in the bag of pot mix, seems to be good as Lolita1234 described in her post.
So is there too much moisture? Or too less? What should I do?

The cutting certainly looks dry to me. If you scratch a bit on the bark and it is green in color the cutting is still alive. I notice that you did not seal the cut areas with wax, the moisture will escape through this untreated cut areas. I hope this is not an expensive variety. Try with cheaper varieties until you get the hang of it. Good luck

Perhaps you can salvage the cuttings by putting them in a closed bag with subtly moistened peat moss / sphagnum moss. In this way cuttings won't dry out and are somewhat protected against rotting... I hope it will work for you. In any case it is my favourite method of rooting cuttings. Good luck again!

I would abort the mission as Vijgenboom said and root them in moss

Many many thanks to all above. Will do as Vijgenboom said

I had really great success with Mai's method this go round (although I think the cuttings I got were naturally strong rooters). I think her secret is soak the cutting for a long time so the cutting has it's own moisture, thus the medium can be drier than usual - prevents rot. Seal the leafing end with wax (no real need to wax the root end). For me, I put the rooting bag inside another ziplock with a slightly damp paper towel in it (which kept the surrounding air extremely humid) until it rooted and started to leaf. I start mine in a water heater closet that stays dark and warm.

After rooting and budding out, I moved the rooted bags into a lidded bin to establish - misting the walls of the bin just a little to provide ambient humidity.

Once in the past, I tried to start cuttings in cups with the cups inside a thin garbage bag. But they dried out. I found a lot of thin plastic (like garbage bags) are breathable so they dry out very quickly. I would definitely make sure your outer bag is thick enough (and sealed) to contain the humidity.

By the way, that white cutting looks a bit like it was dead/dried out before you ever started rooting ??? 

Good luck to you.
